Popis:	In order to respond to the increased demand for clean energy without harming the atmosphere through polluting emissions, Energy production from the hydrogen combustion become largely used. This work presents a numerical study of the injection conditions effect on the structure of the H2-Air diffusion flame. The aim is to reproduce a practical case of non-polluting combustion and resulting in very high temperatures. The configuration is composed of two axisymmetric coaxial jets, as can be found in the diffusion burners. A presumed probability density function (PDF) approach is used to describe the chemistry-turbulence interaction. K-epsilon model of turbulence is used. Particular attention is given to phenomena anchoring or blowout of the flame.
